fin object of my invention is to providex a coke-oven battery inwhich'sulostantially all countertlow between adjacent ducts andregenerators carrying fuel gas and air and waste'gases is avoided.

Y fr further object of my inventionis to pro-l The arrangement of the regenerators in two rows, one ofwhich always transmits air and gas, permits the number of regenerartorsterially simp'lilies the construction of the re` generators and theirconnections to the several horizontal lues.v rEhe details otconstruction and operation of the coke-oven battery of my invention willnow be described in connection with the accompanying drawings, in whichFigure l is a view inlongitudinal section of a portion of the batterytaken on lines C-C and D-D of Fig. 3;

Referring particularly to Figs. l, 3 and 4, a horizontal coke-ovenbattery l, constructed in accordance with myy invent-ion. lcomprises aseries of alternately disposedpcoking chambers 2 and heating walls 3that may be of any desired number. By way otexample, the present batteryis'provided with five coking chambers or ovens with their associatedwiens battery. It may be assumed that fuel walls are a plurality ofcrosswise regenerators 4 and 5 that are respectively arranged in tworows, the rows extending lengthwise of the battery. Each regeneratorextends substantially half the width of the battery and the rows ofregenerators are separated by a partitionwall 6. As best shown in Fig.5, the rows of regenerators do not coincide but are ofl'est in suchmanner that one regenerator of each row is located beyond the endregenerator of the other row. The purpose of this arrangement will behereinafter apparent from a further description.-

Each heating wall 3 is provided with a series of llame flues 7twenty-seven being shown by way of example. Each flame flue is connectedat the top through a port 8 to one of two upper horizontal flues 9, eachof which extends approximately half the length of the wall. Each flameflue 7 is also connected at the bottom thereof through ducts 10 and 11,respectively, to two lower horizontal flues 13 and 14 that extend`substantially the entire length of the heating wall.

Each of the lower horizontal flues 13 and 14 is connected to one of theregenerators 4 or 5, as the case may be, by ducts 15. It may be notedthat the flame flues 7 of alternate walls are connected through thelower horizontal flues 13 and 14 to regenerate-rs 4 while the llameflues of the other walls are connected to regenerators 5. As shown inFigs. 1, 3 and 4, the upper horizontal flue's 9 of adjacent walls areconnected by crossover flues 18 whereby the flame flues of adjacentwalls are connected in series, the walls being thus arranged in pairsAThe connections between the several regenerators of the respective rowsto the lower horizontal flues 13 and 14 and through the ducts 10 and 11to the flame flues 7 and the connections whereby the Walls are arrangedin pairs is clearly shown in Fig. 6, portions of the several ducts andpassageways being omitted for the sake of clearness.

The battery is alsoprovided with gas guns 20 by means of which rich gasmay be supplied to each of the flame flues 7 through a nozzle 21 locatedin a recess-22 in the bottom ofthe flue.

The operation of the battery will be described in. connection with Fig.6, the operation of one pair of heating walls being typical of theoperation of the remainder of the gaf", such as producer gas or otherlean gas, and air are being supplied through regenerators 4 to the lowerhorizontal flues 13 and 14 for distribution to the several flame flues 7of one of the heating walls 3. The combustibleA through the ducts 8 intothe upper horizontal flues 9 and through the cross-over flues 18 intothe upper horizontal flues 9 of the adjacent wall. The hot gases ofcombustion pass downwardly through the flame llues 7 and ducts 10 and 11of the second wall into the horizontal flues 13 and 14. rfhey then passthrough the ducts 15 into the regenerators 5 where they are dischargedinto the stack in the usual manner.

' The direction of operation is periodically reversed in accordance withusual practice. Air and gas are then supplied through the regenerators 5which have been previously heated by hot waste gases and the conditionsare reversed in that combustible materials burn upwardly in the secondwall and pass downwardly through the flame flues and connectedpassageways and out to the stack through the regenerators 4. Thearrangement of the regenerators 5 for carrying gas and air is the sameas that of the rcgenerators 4 under similar conditions describedbelow.

As indicated by the respective legends A, G and WG, Figs. 4 and 5,referring to air, gas and waste gas, in the direction of operation inwhich air and gas are supplied to the generators 4, the air and gasregenerators are arranged in pairs whereby partition walls between themembers of each pair may be substantially eliminated since it is notnecessary thatthe regenerators be separate. Accordingly, while theregenerators have been indicatedgcnerally in Fig. 5, for example, asseparate regenerators, the several pairs of regenerators may in practicebe combined.

-When coke oven gas or other rich gas is used as fuel, the operation isas above decribed except that the gas is supplied directly to the flameflues without being heated by the regenerators and that all of theregenerators in one row carry air while the other row carries wastegases.

The arrangement of the regenerators in offset rows enables tworegenerators that are in alincment and one of which is transmitting airor gas, as the case may be, and the other of which is transmitting wastegas, to be connected to adjacent horizontal flues that are, however,connected to the flame flues of different walls. It will be noted, also,from an inspertion of Fig. G, the wz te gases and fuel gas or air inadjacent flues are always passing in the same direction whereby there isno counterflow between them. This arrangement also insures that there isno counterflow between adjacent regenerators carrying fuel gas and wastegas, respectively, since in, either direction of operation all of theregenerators in one row carry air or fuel gas While the regenerators inthe. other row carry waste gases.

It will be appreciated that the arrangement of the regenerators and theconnected passageways permits the construction of a cokeadjacent heatingwalls having flame flues therein, means for connecting the flame iiuesof one wall in series with those of the other wall, two parallel rows ofregenerators beneath said walls, each regenerator extending about halfthe length of one of said heating walls, means for communicablyconnecting the flame flues of one of said walls to two adjacentregenerators in one of said rows andv means for eominunicably connectingthe flame flues of the. other wall to two regenerators in the other rowthat arestaggered with respect to the first-mentioned two regenerators.
